All cylinders can drop the a valve seat number 4 is the usual one it is the last cylinder in the cooling line it runs hotter. Mine did it at 148,000 miles replaced pistons, rings, rod bearings and a remaned head cost $500 bucks. Runs good only problem now is it use to much oil got to figure that out.

I guess my turn came around and I just dropped the valve seat as well. Sadly I ignored the warning and I was thinking it was something else related regarding misfire #4 even though I changed plugs, wires and coil. Last night I heard that familiar rattle, that I was expecting sooner or later.
Will be taking it apart to see if I can get it fixed.

A very common problem on the 2000–2004 Ford Focus with the 2.0L SPI SOHC engine is the tendency to drop a valve seat.[42] European models don't have this problem, as only the North American Focus was available with the SPI engine. These engines usually drop a valve seat with no warning, for no reason, even if the engine has been well maintained. With most dropped valve seat cases, a seat drops on the number 4 cylinder, with the next most common being the number 2 cylinder. With the factory valve seats, the typical life of the 2.0L SPI in the Focus is about 100-120k miles,[43] but it can happen as early as 70k miles. When the valve seat drops out of the cylinder head, it falls into the cylinder and mashes up the piston and cylinder head. In some cases, the valve seat will exit the cylinder it dropped in and be sucked into other cylinders via the intake manifold until its obliverated. A valve seat dropping into the cylinder can, and sometimes will, scar the cylinder wall up and bend the piston connecting rods. When repairing an SPI with a dropped valve seat, it is very important to remove the intake manifold and have it thoroughly cleaned before bolting it up to a new cylinder head. If not cleaned, trapped particles in the manifold from the dropped valve seat will enter the repaired engine and scar the cylinder walls and sometimes ruin the new cylinder head. The best solution for avoiding the dropped valve seat problem is to purchase and install a new cylinder head that has had the valve seat problem fixed.

found it on wikipedia.com hope it helps out on u SPI drivers =D

When mine started going bad, it would idle ruff sometimes, and spit during cruising speeds sometimes, and sometimes it didn't want to start. Other times it ran great and you would think nothing is wrong with it.

You can ask anyone who knows me, I took very, I mean very good care of the car. Still happened to me.

I got the same problem it happened at about 125k miles. I knew something was wrong cause I recieved a cel for the intake manifold runner control. It would idle really rough and at times it would just lurch while applying throttle. Towards the end the car would keep shutting off mid-drive. Then finally one day it just started making this awful noise. I knew it was done for then.

My SPI Escort did @ 173k miles, dropped #4, fixed it by adding a USED piston/rod from a JY motor, did not remove motor, new bearings, etc. Running good now

My 2002 SPI Focus that I just picked up a few days ago for $400 did the same thing, dropped a vlv seat on #4 @ 98k miles, ordered 4 new pistons and remaned head, again doing a motor in car rebuild. Total cost for BOTH cars will be $1000 to fix ($500 each). This car will be worth $4k when im done with it but I may keep it as a DD or sell the escort.
